Enhancing patient and organizational readiness for cardiovascular risk reduction among Black and Latinx patients living with HIV: Study protocol.

Cardiovascular disease (CVD) is an increasingly important cause of morbidity and mortality among people living with HIV (PLWH) now that HIV is a manageable chronic disease. Identification and treatment of comorbid medical conditions for PLWH, including CVD and its risk factors, typically lack a critical component of care: integrated care for histories of trauma. Experiences of trauma are associated with increased HIV infection, CVD risk, inconsistent treatment adherence, and poor CVD outcomes. To address this deficit among those at greatest risk and disproportionately affected by HIV and trauma-i.e., Black and Latinx individuals-a novel culturally-congruent, evidence-informed care model, "Healing our Hearts, Minds and Bodies" (HHMB), has been designed to address patients' trauma histories and barriers to care, and to prepare patients to engage in CVD risk reduction. Further, in recognition of the need to ensure that PLWH receive guideline-concordant cardiovascular care, implementation strategies have been identified that prepare providers and clinics to address CVD risk among their Black and Latinx PLWH. The focus of this paper is to describe the hybrid Type 2 effectiveness/implementation study design, the goal of which is to increase both patient and organizational readiness to address trauma and CVD risk among 260 Black and Latinx PLWH recruited from two HIV service organizations in Southern California. This study is expected to produce important information regarding the value of the HHMB intervention and implementation processes and strategies designed for use in implementing HHMB and other evidence-informed programs in diverse, resource-constrained treatment settings, including those that serve patients living in deep poverty.

Super-heavy fermion material as metallic refrigerant for adiabatic demagnetization cooling

Low-temperature refrigeration is of crucial importance in fundamental research of condensed matter physics, as the investigations of fascinating quantum phenomena, such as superconductivity, superfluidity and quantum criticality, often require refrigeration down to very low temperatures. Currently, cryogenic refrigerators with $^3$He gas are widely used for cooling below 1 Kelvin. However, usage of the gas is being increasingly difficult due to the current world-wide shortage. Therefore, it is important to consider alternative methods of refrigeration. Here, we show that a new type of refrigerant, super-heavy electron metal, YbCo$_2$Zn$_{20}$, can be used for adiabatic demagnetization refrigeration, which does not require 3He gas. A number of advantages includes much better metallic thermal conductivity compared to the conventional insulating refrigerants. We also demonstrate that the cooling performance is optimized in Yb$_{1-x}$Sc$_x$Co$_2$Zn$_{20}$ by partial Sc substitution with $x\sim$0.19. The substitution induces chemical pressure which drives the materials close to a zero-field quantum critical point. This leads to an additional enhancement of the magnetocaloric effect in low fields and low temperatures enabling final temperatures well below 100 mK. Such performance has up to now been restricted to insulators. Since nearly a century the same principle of using local magnetic moments has been applied for adiabatic demagnetization cooling. This study opens new possibilities of using itinerant magnetic moments for the cryogen-free refrigeration

Comprehensive annotation of the Parastagonospora nodorum reference genome using next-generation genomics, transcriptomics and proteogenomics

Parastagonospora nodorum, the causal agent of Septoria nodorum blotch (SNB), is an economically important pathogen of wheat (Triticum spp.), and a model for the study of necrotrophic pathology and genome evolution. The reference P. nodorum strain SN15 was the first Dothideomycete with a published genome sequence, and has been used as the basis for comparison within and between species. Here we present an updated reference genome assembly with corrections of SNP and indel errors in the underlying genome assembly from deep resequencing data as well as extensive manual annotation of gene models using transcriptomic and proteomic sources of evidence (https://github.com/robsyme/Parastagonospora_nodorum_SN15). The updated assembly and annotation includes 8,366 genes with modified protein sequence and 866 new genes. This study shows the benefits of using a wide variety of experimental methods allied to expert curation to generate a reliable set of gene models

SARS-CoV-2 infection produces chronic pulmonary epithelial and immune cell dysfunction with fibrosis in mice

A subset of individuals who recover from coronavirus disease 2019 (COVID-19) develop post-acute sequelae of SARS-CoV-2 (PASC), but the mechanistic basis of PASC-associated lung abnormalities suffers from a lack of longitudinal tissue samples. The mouse-adapted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain MA10 produces an acute respiratory distress syndrome (ARDS) in mice similar to humans. To investigate PASC pathogenesis, studies of MA10-infected mice were extended from acute to clinical recovery phases. At 15 to 120 days post-virus clearance, pulmonary histologic findings included subpleural lesions composed of collagen, proliferative fibroblasts, and chronic inflammation, including tertiary lymphoid structures. Longitudinal spatial transcriptional profiling identified global reparative and fibrotic pathways dysregulated in diseased regions, similar to human COVID-19. Populations of alveolar intermediate cells, coupled with focal up-regulation of pro-fibrotic markers, were identified in persistently diseased regions. Early intervention with antiviral EIDD-2801 reduced chronic disease, and early anti-fibrotic agent (nintedanib) intervention modified early disease severity. This murine model provides opportunities to identify pathways associated with persistent SARS-CoV-2 pulmonary disease and test countermeasures to ameliorate PASC., After recovery from acute SARS-CoV-2 infection, mice exhibit chronic lung disease similar to some humans, allowing for testing of therapeutics

The Senatus Consultum de Cn. Pisone Patre. Text, translation and commentary

The Senatus Consultum de Cn. Pisone Patre is a senatorial decree issued in AD 20 following the trial of Gnaeus Calpurnius Piso, the governor of Syria, who was accused of rebellion against Tiberius following the death of his heir Germanicus. It survives on several inscriptions and is among the most important documents from the early Principate. This new edition, with translation and commentary, sets the text within its contemporary context, considering it alongside other texts (including Tacitus' Annales), coins, and monuments, focusing upon the development of Tiberian political discourse. It explores how contemporary observers (including Valerius Maximus and Velleius Paterculus) understood and contributed to the shaping of dynastic rule at Rome after the death of Augustus in AD 14. It analyses how the Principate continued to evolve under his successor Tiberius, and explores the role of different individuals and groups in negotiating these political changes
